The pipelines of my system keep filling with water from the tanks that are being aerated. What could be the cause?
.
One of the main causes of this problem is a faulty or missing non return valve in the discharge line. Thus, when the blower stops, the pressure remaining in the discharge line tracks back through the damaged non return valve and out to atmosphere through the blower. Water is then able to travel back up the discharge line when it will at least find it’s own level and in some instances will actually siphon back into the casing of the blower itself.
Should this occur, the unit should be isolated and appropriate checks and remedial action taken as soon as possible. If water has been ingested into the blower, it should then be run under normal load for a period of time to dry out the inner casing and rotors. Following this procedure will avoid rusting of the blower internals which can lead to serious damage and possibly complete seizure.
